Abstract
The Pouni region of Burkina Faso is characterised by its Palaeo-Proterozoic
formations and Birimian terrains. In contemporary geological studies, the
integration of advanced technologies is becoming crucial to improving the
accuracy and efficiency of mapping. This article presents an analysis of the
Pouni area using remote sensing and Geographic Information Systems (GIS) to
produce detailed maps of lithological formations. The study is based on
satellite data from the Landsat 5 programme, as well as geological and
topographical data. Image processing methods such as colour composition (bands
TM7, TM4, TM2) and Principal Component Analysis (PCA) were used to highlight
lithological contours and identify distinct geological formations. In addition,
the digitisation of lineaments, enhanced by directional filters such as Sobel's,
provided a clearer understanding of the geological structures. The results
obtained indicate that the integration of satellite data and GIS significantly
improves the accuracy of geological mapping, offering significant savings in
terms of time and resources. However, field validation remains essential to
confirm these results and refine interpretations.
